外文摘要：In this paper， the results of a study into the use of H infinity and LQG/LTR methods for the design of robust feedback control laws to provide satisfactory performance despite of system uncertainties in grinding circuit are presented。 Robust controllers are designed to give accurate control of ball mill throughput and product fineness。 The design is based on a linear model obtained from a phenomenological simulator of grinding circuit。 Robustness is a major issue because changes in operating conditions are not included in the design model。 Robust stability and performance are assessed from singular values plots。 Simulations show a better performance of H infinity synthesis when compared to a LQG/LTR controller。
